NIANUFACTURE OF WIRE-GLASS.

Specicaton of Letters Patent.

Patented Nev. 21,1905. y

Application filed July 22,1904. Serial No. 217,707.

To all, whom, t T12/(ty concern:

Be it known that I, ARTHUR J. BALDWIN, a citizen of the United States, residing at East Orange, Essex county, in the State of New Jersey, have invented a new and useful Improvement in the Manufacture of Wire-Glass, of which the following is a specification.

In the accompanyingdrawing, which makes part of this specification, the figure represents a vertical section through a form of apparatus adapted to carry out my improved manufacture of wire-glass.

The purpose of my invention, generally stated, is to devise a method wherein the wire may be accurately centered in the solid sheet of glass instead of sandwiched in between two half sheets made separately.

A further purpose of my invention is to air-polish the sheet in its passage from the rolls to the receiving-table and to so harden the surface of the same that it will receive no marks from the surface of the receiving-table.

In carrying out this process I preferably employ the following apparatus:

A A are forming-rolls between which the sheet of glass is made. They are located above a receiving-table B, which may be driven by any suitable pinion C and rack D. Located in the converging space between the two rolls A A is a water-cooled wire-guide E. This is preferably provided with lifting-chains F F, by which the same can be raised after the wire has been correctly started in the center of the glass sheet. i

G is the wire mesh to be incorporated into the glass, and H H the batch in which the glass sheet is to be rolled, and this batch is preferably poured on each side of the wireguide E; but the batch flows down and unites in a unit mass of glass immediately below the wire-guide.

I is an air-blast to regulate the temperature of the sheet as may be desired after it emerges from the roll-pass.

The invention is practiced in the following manner: A suitable pouring of glass is placed on either side of the wire-guide. The wire is held in readiness and as soon as the glass has flowed down toa position at or just in advance of the bite of the rolls the wire is released and falls by gravity into the center of the mass of glass, and as the rolls are started a sheet is formed dragging along' in its center the contained and initially-embedded wire. At this juncture, if desired, the water-cooled wireguide can be raised, so as to be no longer exposed to the heat of the glass. The continued rotation of the rolls completes the sheet of glass with the wire contained therein, and the sheet drops by gravity upon the receivingtable B, which carries the same away. Meantime, if found advantageous, the sheet can be exposed to the air-blast I.

The advantages of my invention will be obvious to those skilled in the art, and some of the valuable features are the following: The glass is made in an integral sheet instead of in fractional parts and by the action of one rollpass alone. No special means are required to incorporate the wire in the center of the sheet except a centering-guide and the aid of gravity in feeding the wire continually downward. I also attach importance, although not absolutely essential, to the presence of the air-blast between the roll-pass and the receiving-table.

Wire-glass made by this process will contain wire accurately located in the exact center of the sheet and the sheet itself will be of the most solid and consistent character without any danger of being lappy.

Having described my invention, I claimd l. An improvement in the art of making wire-glass which consists in forming the sheet in a single roll-pass and introducing the wire out of contact with the glass and simultaneously with the formation of said sheet to the center of said roll-pass.

2. An improvement in the art of making wire-glass which consists in forming the sheet in a single roll-pass and introducing the wire by gravity simultaneously with the formation of said sheet to the center of said roll-pass.

3. An improvement in the art of making wire-glass which consists in forming the sheet in a single roll-pass and introducing the wire by gravity and simultaneously with the formation of said sheet to the center of said rollpass and subjecting the sheet upon its delivery from the roll-pass to the action of an airregulating blast.

4. In the manufacture of wire-glass the combination of sheet-forming rolls and means for screening the wire from the glass untilv the wire reaches substantially the sheet-forming portion of the roll-pass.
